DROSHA and DICER protein expression across the menstrual cycle in the endometrium of fertile and infertile women. Immunoscoring of DROSHA in the (A) fertile and (B) infertile luminal epithelium, glandular epithelium, and stroma during the P, ES, MS, and LS phases. Immunoscoring of Dicer in the (C) fertile and (D) infertile luminal epithelium, glandular epithelium, and stroma during the P, ES, MS, and LS phases. Data are presented as mean ± SEM (n=5/group). Abbreviations: P, proliferative; ES, early secretory; MS, mid-secretory; LS, late-secretory; SEM, standard error of the mean. One-way ANOVA for significance (*p<0.05, **p<0.01, ***p<0.001).
